Problem Structuring and Analytical Frameworks Questions
The ability to convert ambiguous business problems into clear, testable, and actionable analytical questions and frameworks. Candidates should demonstrate how to clarify the decision to be informed and success metrics, break large problems into smaller components, and organize thinking using hypothesis driven approaches, issue trees, or mutually exclusive and collectively exhaustive groupings. This includes generating hypotheses, identifying key drivers and uncertainties, specifying required data sources and any necessary transformations, choosing analytical methods, estimating effort and impact, sequencing and prioritizing analyses or experiments, and planning next steps that produce evidence to guide decisions. Interviewers also assess evaluation of trade offs, recommending a decision with a clear rationale, effective communication of structure and findings, and comfort operating with incomplete information. The scope includes applying general case structuring as well as specialized frameworks such as growth funnel analysis that maps acquisition, activation, revenue, retention, and referral, audience segmentation and competitive assessment frameworks, content and channel strategy, and operational step by step approaches. For more junior candidates the emphasis is on clear structure, systematic thinking, strong rationale, and prioritized next steps rather than exhaustive optimization.

You're supporting a new product feature launch. Stakeholders ask 'Did we succeed?'. Define one primary success metric for day-7 success, two supporting metrics that explain the mechanism, and two guardrail metrics to monitor negative side effects. For each metric, describe how to compute it from event data and suggest realistic tolerance thresholds.

Design an analytical framework to estimate customer Lifetime Value (LTV) in the presence of right-censoring and changing customer behavior over time (non-stationarity). Specify data required, model choices (e.g., survival analysis, BG/NBD, parametric vs non-parametric, hierarchical/Bayesian), how to quantify uncertainty, and how to present results to business stakeholders for decision-making.

Case: Monthly Active Users (MAU) dropped 12% in the last quarter. As the lead data scientist, outline an end-to-end investigation and action plan: frame the decision(s) to be made, generate hypotheses, list required datasets and transformations, propose analytical methods (diagnostics, causal tests, experiments), sequence and prioritize tasks, estimate effort and impact, and state what recommendation(s) you might make under different findings.

A referral program rewards both referrer and referee. Describe a robust approach to measure incremental revenue attributable to the program while accounting for selection bias (users who refer may be more valuable) and seasonality. Include data design, an identification strategy, potential experiments, and metrics to report (e.g., incremental revenue per referral).

Map the growth funnel (acquisition, activation, revenue, retention, referral) for a mobile consumer app. For each stage list 2–3 concrete metrics and the most reliable data source(s) you would use to measure them. Then recommend two quick experiments to improve activation and explain how you would measure lift.
